![Question](https://mbworld.org/forums/images/icons/icon5.gif)
So my 2015 C63 just had a recall done that apparently required reprogramming the engine management unit. The recall number on the invoice was 4911.
Any ideas that that recall achieved?
thanks!

I just made an appointment to bring in my 2016 to take care of some rattles and buzzing panels and was notified of a new campaign 2019020003 issued in February of this year which is a new ECM program. I asked and the service advisor had no info. I plan on inquiring some more about it when I'm there.

After reading this thread I made an appointment for the ecu/tcu updates tomorrow as well. I’ll report back with noticeable differences.

So the recall is the 2019020003 number and it’s an ecu/tcu software update that takes about 30-40 mins to flash. The 4911 the op mentioned is just a billing reference number on his invoice, not an actual recall number. I’ll report what I notice after I drive it around, but hopefully like another member mentioned in a different thread, it will drive like a completely different car with quicker/smoother shifts.

Well I’ve given it a couple of days, and it’s very odd !
1, the engine at idle is smoother. Not what I expected.
2, the gearchange points are different. Changes up earlier in lower gears.
3. the problem of the cold start high idle sometimes not working appears fixed.
4, the exhaust pops and bangs appear reduced and quieter.
5, average MPG has gone up by about 1.5 mpg (UK gallons)
YMMV buts that’s what I found.
Thinking out loud.. I wonder if they also blocked OBD tuning with this update? New private key maybe?

'15 C63S
Reason I say that is because my '15 C63S sedan had the ECU update done last year, and there were no recalls/campaigns needed when it was in for service late last week.

Pure speculation on my part, but I'm wondering if this is just the same software update that others have already done. Maybe they are now just doing it to all the older cars that have yet to be updated.

After looking over my warranty history with the service writer, I had my ecu updated twice already October being the last time right before I bought it. This is a new update/recall.

I just called my dealer (in Toronto, Canada). They said no outstanding recalls.
I also got the Exhaust/Transmission ECU update done in November 2017.

I ran across a thread about software updates and the consistency or lack thereof with respect to dealers installing them. Just do a search. The fact is that I have a one year/old 2018 C63s AMG coupe that received an update of the engine management software a couple of days ago during a r-o-u-t-i-n-e 10,000 mile service and it profoundly affected the way transmission shifts - smoother, quicker and lower down in the rpm range. How can I be the only one?

Even though it says recall on the bill it might not be an official mandated recall and just a software update on your next scheduled maintenance. I would ask for the software update and see if what you have on your car currently matches the latest one available. Give them the number to reference it in the bill in this thread. I don't see this as an official recall on any website.

I have noticed smoother, quicker shifts lower in the rpm range (throttle dependent) and the car idles smoother/quieter as well in s mode. Pops and crackles seem to be the same in s+ as my last software, but I only briefly tested it and haven’t played with it too much yet.

I guess I'll have to wait to get my car back to see if I observe the same as others have. I ran a VMI report in October 2018 and all campaigns were complete. This is the first campaign since then.
